Abstract

A Peer-to-Peer (P2P)-based network apparatus and system is provided. The P2P-based network apparatus may sense the movement of a mobile station (MS), select a candidate proxy, and change a proxy of the MS to the candidate proxy.

Claims

1. A Peer-to-Peer (P2P)-based network apparatus, the apparatus comprising:

a movement sensing unit configured to sense movement of a mobile station (MS);

a candidate proxy selection unit configured to select a candidate proxy for connection with the MS, in response to movement of the MS being sensed;

a data packet forwarding unit configured to forward a data packet destined for the MS to the selected candidate proxy; and

an information control unit configured to delete information about the MS after the data packet is forwarded.

2. The P2P-based network apparatus of claim 1, wherein the movement sensing unit is further configured to sense the movement of the MS based on the location of the MS.

3. The P2P-based network apparatus of claim 1, wherein the movement sensing unit is further configured to sense the movement of the MS based on at least one of a change of an Internet Protocol (IP) address of the MS, a change of a network interface, and whether a handover occurs.

4. The P2P-based network apparatus of claim 1, wherein the candidate proxy selection unit is further configured to:

determine whether to change a proxy of the MS; and

in response to a proxy change being determined, select the candidate proxy based on state information of each of a plurality of neighbor proxies.

5. The P2P-based network apparatus of claim 1, wherein the data packet forwarding unit is further configured to:

forward a migration request message to the candidate proxy,

set a tunnel with the candidate proxy, and

forward the data packet to the candidate proxy.

6. The P2P-based network apparatus of claim 5, wherein, in response to a confirm migration request message being received from the candidate proxy, the data packet forwarding unit is further configured to forward address information of the candidate proxy to the MS.

7. The P2P-based network apparatus of claim 1, wherein:

the data packet forwarding unit is further configured to forward a proxy change request message to the MS; and

a data session between the MS and the candidate proxy is configured to be set through the forwarding of the proxy change request message.

8. The P2P-based network apparatus of claim 7, wherein, in response to the data session between the MS and the candidate proxy being set, the data packet forwarding unit is further configured to forward a data packet that was previously forwarded to the candidate proxy, to the MS.

9. The P2P-based network apparatus of claim 7, further comprising a message forwarding unit configured to forward an endpoint change request message to at least one Correspondent Peer (CP) connected to the MS in response to the data session between the MS and the candidate proxy being set.

10. The P2P-based network apparatus of claim 1, wherein the data packet forwarding unit is further configured to:

receive and forward the data packet from and to the MS and at least one CP connected to the MS; and

share the data packet with the MS and the at least one CP.

11. A Peer-to-Peer (P2P)-based network apparatus, the apparatus comprising:

a data packet receiving unit configured to receive a data packet from a proxy configured to sense movement of a mobile station (MS) and determine a proxy change of the MS;

a packet buffering unit configured to buffer the received data packet;

a message receiving unit configured to receive a proxy registration request message from the MS; and

a data packet forwarding unit configured to forward the buffered data packet to the MS, in response to the MS being registered.

12. The P2P-based network apparatus of claim 11, wherein the message receiving unit is further configured to receive a migration request message from the proxy configured to determine the proxy change, the migration request message comprising information about the MS and a CP list.

13. The P2P-based network apparatus of claim 11, wherein the data packet receiving unit is further configured to:

forward the buffered data packet to the MS; and

share the data packet with the MS and at least one CP connected to the MS.

14. A Peer-to-Peer (P2P)-based network apparatus, the apparatus comprising:

a message receiving unit configured to receive a proxy change request message from a proxy configured to determine a proxy change of a mobile station (MS) and select a candidate proxy;

a registration setting unit configured to set a registration of the P2P-based network apparatus in the selected candidate proxy; and

a data packet receiving unit configured to receive a data packet, buffered in the selected candidate proxy, in response to the registration being set.

15. The P2P-based network apparatus of claim 14, further comprising an information forwarding unit configured to forward information to the proxy determining the proxy change, the information being used to sense movement of the MS.

16. The P2P-based network apparatus of claim 15, wherein the information comprises at least one of a change of an IP address of the MS, a change of a network interface, and whether a handover occurs.

17. The P2P-based network apparatus of claim 14, wherein the registration setting unit is further configured to:

receive the proxy change request message,

forward a proxy registration request message to the selected candidate proxy, and

set the registration in the candidate proxy.

18. A Peer-to-Peer (P2P)-based network apparatus, the apparatus comprising:

a message receiving unit configured to receive a migration request message from a proxy and a proxy registration request message from a mobile station (MS), the proxy sensing movement of the MS and determining a proxy change of the MS; and

a session setting unit configured to set a data session with at least one Correspondent Peer (CP) connected to the MS, in response to the MS being registered.

19. The P2P-based network apparatus of claim 18, further comprising a data packet receiving unit configured to share a data packet with the at least one CP and the MS, in response to the data session with the at least one CP being set.

20. A Peer-to-Peer (P2P)-based network system, the system comprising:

a mobile station (MS);

a proxy configured to;

sense movement of the MS;

determine whether to change a proxy of the MS; and

in response to the proxy change of the MS being determined, select a candidate proxy;

the candidate proxy configured to;

buffer a data packet, forwarded from the proxy; and

in response to the MS being registered, forward the buffered data packet to the MS; and

a Correspondent Peer (CP) configured to terminate a data session with the proxy and share the data packet with the candidate proxy, in response to an endpoint change request message being received from the proxy.
